Introduction

Much of the work done at Google, and in many organizations, is done collaboratively by teams. The team is the molecular unit where real production happens, where innovative ideas are conceived and tested, and where employees experience most of their work. But it’s also where interpersonal issues, ill-suited skill sets, and unclear group goals can hinder productivity and cause friction.

Following the success of Google’s Project Oxygen research where the People Analytics team studied what makes a great manager, Google researchers applied a similar method to discover the secrets of effective teams at Google. Code-named Project Aristotle - a tribute to Aristotle’s quote, "the whole is greater than the sum of its parts" (as the Google researchers believed employees can do more working together than alone) - the goal was to answer the question: “What makes a team effective at Google?”
